题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.
 
The argument above requires which of following assumptions?

选项:

A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.
C、The pretax price of a pack of cigarettes gradually decreased throughout the year before and the year after the tax increase.
D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.
E、As the after-tax price of a pack of cigarettes rises, the pretax price also rises.

A new drug, taken twice daily for one month, is an effective treatment for a certain disease.  The drug now most commonly prescribed for the disease occasionally has serious side effects such as seizures; in field tests, the new drug's side effects, though no worse than mild nausea, turned out to be much more frequent.  Nevertheless, the new drug is clearly preferable as a treatment, since _____.
请问张慧雯老师，我可以理解e是对的，然后现在对abd两个选项有疑问,先说说我对题目的理解，一个新药对一种病的治疗很有效，但是他偶尔会有一些副作用，在最近的实验里它的副作用变得更加频繁，但是他仍然是一种更受欢迎的治疗方式，因为？ b选项的问题是不是因为他违背了原文背景信息，因为他已经说了就是他有副作用，所以排除？我d选项有问题的理由是他说有人接受了有效的治疗就不会再得这种病了，我当时想的是就说明这个药效果很好，药到病除，就算有副作用也不妨碍他很受欢迎；a选项说有n症状的人不会再吃这个药了，但是这个现象是普遍的而不是个例，所以排除？请老师看看我其他几个选项排除的理由中的漏洞。

It can be inferred from the passage that a chain of volcanoes created by a mantle plume would most likely be characterized by
             
 
请问张慧雯老师，听了前面的录音还是有一个点没有理解就是c选项，您说第二段没有讨论边界的而是板块内部所以干掉，However, certain "misplaced" volcanoes far from plate edges result from a second, independent mechanism that cools the deep interior of Earth.+后面一顿说原理的细节同时也没有讨论边界的问题得出的， Because the source of a hot spot remains fixed while a surface plate moves over it, over a long period of time an active plume creates a chain of volcanoes or volcanic islands, a track marking the position of the plume relative to the moving plate. 同时这句话也没有出现边界的描述所以干掉呢？之前我觉得有点沾边是因为Because the source of a hot spot remains fixed while a surface plate moves over it, 这句话就是什么东西 在那个上面，然后就对应了c，至于b，over a long period of time他是说了很长时间，但是感觉还行吧，没有觉得有问题，主要纠结c

请教张慧雯老师，本题我的定位点和思路：the time it takes a particle to tunnel through a barrier increases with the thickness of the barrier until tunneling time reaches a maximum; beyond that maximum, tunneling time stays the same regardless of barrier thickness 未达到最大时，厚度越大时间越长，那不就是厚度越大速度越慢吗？所以我选的B ，请老师指出我的问题
